Touch phones has become more and more popular recently. Pocket Kanji is now updated to support touch buttons. All components in Pocket Kanji react to push.
Japanese word conversion is improved too. Romaji doesn't need to be complete anymore to be recognized as a japanese word. Dictionary shows all words starting with that strings. For example, "tenk" gets words like "tenki" (てんき) and "tenka" (てんか).
